I have been playing the game for one season already, now I'm in the early Summer.I have been talking to all the villagers and give them giftsbut it doesn't seem like the heart level is increasing at all...I still have no heart from any of them

the Bachelors' heart aren't increasing too though I have been giving them gift that they loveDo I need to give them gift on consecutive days?Is there a way to increase the heart faster?
